Hello Joshua,

Sorry for not following up quickly on this one.

Are these panic still happening? It might be worth reporting this upstream.

We probably need to know more about the printers installed on the
server.

Also, the output of "testparm" might help (better than smb.conf
content as settings that  have their default value will be ignored).
